GS4A021742DBT Description

The GS4A021742DBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying conditions. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 17.4 kΩ and an absolute tolerance of ±0.5%, ensuring exceptional accuracy. The network operates over a wide temperature range of -70°C to +125°C, with a derated power range up to 125°C, making it suitable for harsh environments. Its ±50 ppm/°C temperature coefficient guarantees minimal resistance drift, while the 100V maximum voltage rating and 0.4W total power dissipation (0.1W per resistor) enhance reliability in high-voltage circuits.

GS4A021742DBT Features
